[build] Add a script for installing db4 

Instead of maintaining not-easily-tested instructions for building BerkeleyDB
in doc/build-unix.md, package the installation as a script in contrib/. This
allows shared usage from a number of contexts, e.g. Docker.

Thanks to @jonasschnelli, @laanwj for feedback.
